I aIMPROVEMENT IN FLUTING-MACHINES The Schedule referred. to in these Letters Patent and making part cf the same To alllfwhom it 'may concern;

Be itknown'that I, FREDERIC HEWITT, of Bloom field,.in the. ccunty of Essex, and State of` New J ersey, have inventeda new and useful Improvement in Filming-Machines; and I do hereby declare that the same, reference being had 'to the annexed drawings,

making apart of this specification, in which- 'Figure 1` is a longitudinal `elevation of my invention, and .e y Figure 2, auend elevation of thsame.

The same let-ters indicate` like parts in both figures.`

'lhenature of my invention consists in 'dispensing with the rollers heretibreused in llutingmachines, and using, instead, two` flat or curved surfaces -or dies, having the necessary andncorrespoiuiing corrugations, flutes, crimps, or other 'patterns formed on their surfaces.; these dies, forming the faces of two boxes or heater-receptacles, one upper and one lower, and

which may be pressed together` in any convenient manner.; said dies -being heated by heaters inserted into the befbre-mentioned boxes or receptacles, so that the material to be tluted, being placed between said dies ,'and pressurebeing applied, ma'yreceive an impression corresponding to the patterns on the dies.

My invention further consists in au apparatus cou-Y renient for transmitting pressure to the `dies and heater boxes, and so arranged that thexparts thereof are out of the way ofthe work to he operated upon. y

To enable others to understand the nature and con- `struction of my invention, I will proceed todescribe it with reference to the drawings, in which- AA are the two heater-bores, the facesotl which, B', are formed with the iiutesv or other patterns intended to be impressed on the material operated up0n. Y Y e :These faces may either be separate pieces from the heater-boxes, to which they may be fastened, -in4 any convenient manner, or they may be made in one piece with them. I l

11 F are the heaters, placed in their receptacles, to

`heat `the dies B B. following is a full, clear, andV exact description of the One of theSebOXea-inthis case the lower, is made fast to the standard M4 and clamp J, the standard Y forming a fulcrum, at E, for the lever G, at` one end of which, at E', are attached the other heater-box' and l die.

At a point, N, intermediate between E and E', is

`a link, I), connecting the lever Cn'ith the lever G,

which has its fulcrum at I, sothat pressure applied at the end, K, of lever G, is transmitted, by link D, to lever G, and so to the heater-box A andA die B.

` The lever() is continued to L, where is attached a spring, H, which 'raises theendv il', and heater-boxv and die, when the pressure lieved.` v l l A weight may be substituted for the spring, it' desired. Y

The hole K, in lever G, is for the purpose of attaching a cord or stirrup, by which'the pressure may on the leverG is rebe applied by the foot, leaving the hands at liberty` G, operated as shown and described.

resonate HEWITT.
